Disclosed embodiments include wearable devices and techniques for detecting cardio machine activities, estimating user direction of travel, and monitoring performance during cardio machine activities. By accurately and promptly detecting cardio machine activities and automatically distinguishing between activities performed on different types of cardio machines, the disclosure enables wearable devices to accurately calculate user performance information when users forget to start and/or stop recording activities on a wide variety of cardio machines. In various embodiments, cardio machine activity detection techniques may use magnetic field data from a magnetic field sensor to improve the accuracy of orientation data and device heading measurements used to detect the end of a cardio machine activity.

A smart wearable device may include a smart ring device. The smart ring device may include a ring that includes a coupling mount.

The electronics unit may generate usage data representative of a movement and a physiological response of a user. In addition, the smart ring device may include a feedback system communicatively coupled to the electronics unit. The feedback system may display information related to the smart ring device.

A wearable device assembly has a housing supporting a controller, display and indicator system thereon. The controller has at least one sensor wherein activity of a user wearing the device is detected. The controller selectively illuminates the indicator system to indicate a level of activity of the user.

Methods, devices, systems, and kits are provided that buffer the time spaced glucose signals in a memory, and when a request for real time glucose level information is detected, transmit the buffered glucose signals and real time monitored glucose level information to a remotely located device, process a subset of the received glucose signals to identify a predetermined number of consecutive glucose data points indicating an adverse condition such as an impending hypoglycemic condition, confirm the adverse condition based on comparison of the predetermined number of consecutive glucose data points to a stored glucose data profile associated with the adverse condition, where confirming the adverse condition includes generating a notification signal when the impending hypoglycemic condition is confirmed, and activate a radio frequency (RF) communication module to wirelessly transmit the generated notification signal to the remotely located device only when the notification signal is generated.

A tissue hydration monitor and method includes a sensor module having a plurality of LEDs positioned to emit a plurality of different wavelengths of light toward the user's skin and a detector that detects light transmitted and reflected through the user's skin to generate signals corresponding to an intensity of detected light at each of the different wavelengths. A processor/controller module generates a baseline hydration level based on the received signals, calculates a relative hydration level, and generates an output indicative of relative hydration personalized to the user. The housing is secured against the user's skin by an adhesive patch or a strap.

An urethral compression apparatus is defined by a semi-cylindrical fenestrated dorsal hood that is worn dorsally on the penis and which is interconnected with a strap to a urethral compressor that is oriented ventrally to apply compressive pressure on the urethra to prevent urine leakage. The dorsal hood and the urethral compressor apply distributed pressure that prevents compromised venous and arterial circulation but eliminate incontinence. The device may be worn continually and is easily removed to allow voiding, then reattached. The fenestration in the dorsal hood (or plural fenestrations as the case may be) allows distribution of pressure to avoid venous and arterial blood flow interruption. The dorsal hood partially encircles the penile shaft and the urethral compressor is oriented ventrally and applies the desired pressure to the soft ventral tissues and the urethra. A strap applies tension between the dorsal hood and the urethral compressor, and thus the necessary compression between these two components.

This invention relates to a method of providing an indication of the oncoming parturition in livestock and an apparatus for carrying out the method. A tail mounted sensor is mounted on the tail of an animal such as a cow or a horse and the tail mounted sensor detects whether the tail is raised or lowered. Each time that the tail is raised by at least a fixed angle of, say 10, for a certain period of time T.sub.1, the sensor records this as a contraction. The sensor then monitors the number of contractions over a given second period of time, T.sub.2. When the number of contractions in the second period of time equal or exceed a certain amount, an alarm is raised. The method and system are such that they can be adjusted for different animals. It is envisaged that less false alarms and less missed births will result as a consequence of this method and apparatus.

Novel tools and techniques for wearable device vital signs monitoring are provided. An apparatus system includes a remote device, and a wearable device in communication with the remote device. The wearable device includes a polychromatic light source, a spectral sensor, a processor, and a non-transitory computer readable medium comprising instructions executable by the processor. The wearable device is configured to illuminate, via the polychromatic light source, a perfused tissue of the body of the patient, receive, via the spectral sensor, a resultant signal from the body of the patient, and determine a spectral property of the resultant signal. The wearable device may then determine a vital sign of the patient based, at least in part, on a lookup table and the spectral property of the resultant signal.

Embodiments of the present invention are directed to a systems and methods for registration of pulse wave signal and determining arterial pressure. A non-limiting example of the system includes a strain gauge sensor. A non-limiting example of the method includes receiving, to a processor, a first pressure pulse signal from a first strain gauge sensor.
